Chapter 1Until now all your programs have been working from top to bottom. Imagine if you were to write a game to guess a secret number from 1 to 100. The entire program would consist of one hundred if statements to account for each turn to check and see if the number chosen is correct; a situation like this is where a loop will come in to play and reduce those one hundred statements into one. A loop is a control structure that allows you to repeat the same sequence of code as long as a given test condition evaluates to true. Every passage through this sequence of code is called an iteration. If you repeat the same sequence of code 20 times, then you have performed 20 iterations. | ||
